                  - Argument-1 may be a literal or data item of any class or category. 
                     	 
                  
- If argument-1 or any data item subordinate to argument-1 is described with the DEPENDING phrase of the OCCURS clause, the
                     contents of the data item referenced by the data-name specified in the DEPENDING phrase is used at the time the LENGTH-AN
                     function is evaluated.

                  - If argument-1 is an elementary data item, the returned value is an integer equal to the length of argument-1 in alphanumeric
                     character positions. 
                     	 
                  
- If argument-1 is a group data item: 
                     		
                      
                        		  
                        - If argument-1 or any data item subordinate to argument-1 is described with the DEPENDING phrase of the OCCURS clause, the
                           returned value is an integer equal to the length of argument-1 in alphanumeric character positions, as a sending data item,
                           determined by evaluation of the data item specified in the DEPENDING phrase in accordance with the rules of the OCCURS clause;
                           otherwise the value returned is an integer equal to the length of argument-1 in alphanumeric character positions. 
                           		  
                        
- The returned length includes the number of implicit FILLER positions, if any, in argument-1.
